Siegfried (ジークフリード, Jīkufurīdo?), also known as Ziegfried, is a non-playable character in Final Fantasy VI. He is a famous Thief, and it is hinted that he is Ultros's rival. Though he does not play an important role in the story, he still appears frequently.
Siegfried makes his first appearance on the Phantom Train, where he disrupts Sabin, Shadow, and Cyan, who are working their way towards the front of the train. Siegfried picks a fight with them when they try to open a treasure chest. He is weak and easily defeated. However, he manages to escape with the treasure anyway.
Though he does not appear in person, Ultros attempts to steal the statues representing the Warring Triad from the Esper Caves in the hopes of earning Siegfried's respect. This is the only time in the game the two are hinted to know each other, but this is not explained in detail.
Siegfried later appears in South Figaro Cave in the World of Ruin, where he follows Gerad and his thieves into Figaro Castle. Celes and Sabin spy him stealing treasure on the way, but he ultimately vanishes once the two enter the castle.
Siegfried's final appearance is in the Dragon's Neck Coliseum, where he remains for the rest of the game. He reveals there was someone trying to disguise themselves as him and urges players not to be fooled by the impostor. This is not further elaborated on. Betting a Megalixir will allow players to fight him, and he is much stronger than before.
The vast difference in strength between the Siegfried found inside of the Coliseum and the one found on the Phantom Train could mean that the Siegfried in the Coliseum is the real one, and the one the party encountered on the Phantom Train is the impostor. However, this does not explain the other encounters. In the SNES version, during the instances where he is helpful he appears as "Siegfried," and when he hinders the player he is called "Ziegfried." This implies that these are two separate characters and explains Siegfried's comment about being impersonated; this distinction is absent in the Advance release. It is possible that the imposter was meant to be Gogo before the sidequest to recruit him was changed in development.

- A Ghost Card in Dissidia Final Fantasy is named Siegfried. The Siegfried ghost is a Level 100 Kefka. A Cyan Gem and a Tintinnabulum can be won through Battlegen with the ghost, the latter a reference to the item the player can win from Siegfried in the Colosseum in Final Fantasy VI. The quote on the card "It seems that an imposter has been masquerading as me recently..." is what Siegfried says to the party in the Colosseum.
- In Dissidia 012, the Ghost Card "Famed Moogle" uses Siegfried's icon. The description references Seigfried: "You know not my name? Everyone knows only the octopus..."
